http := TChilkatHttp.Create(Self);

if (success <> 1) then

  end;

//  Set the SessionLogFilename property so that the Chilkat HTTP component
//  logs the exact HTTP requests and responses to a log file.

//  The SessionLogFilename may be used with any of the HTTP
//  methods for sending GET, POST, PUT, DELETE, HEAD, etc.
http.SessionLogFilename := 'c:/temp/httpSessionLog.txt';

//  Try a simple HTTP GET and then examine the session log:

html := http.QuickGetStr('http://www.chilkatsoft.com/httpTest/abc.html');
if (Length(html) = 0 ) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

//  Here are the contents of the session log file after doing
//  the GET request:
